Trying to build and actually use the FSF version of GDB on OS X, if the build actually succeeds has so many caveats that anything beyond "toy" programs is useless. Things like gdb not supporting dynamic libraries (at least the last time I checked) are sort of show-stoppers for me.

The qt-debugging helpers in 4.7.x still seem to work, at least more or less. I can see a QString finally and a std::string pretty easily. Still no true debugging of vectors, sets, maps and really anything else. I should state that I use OS X 10.6.8 still which is where some of these problems seem to lie. I have not actually tried 10.8 debugging under Qt Creator yet.

<opinion>The sad truth for me is that when I really need to debug deep into my code I fire up a VM with Windows and Visual Studio. I may not like how VS operates but the debugger seems to be able to show all everything that I need, including STL containers and most Qt classes. </opinion>
